How to install/use PhysX?

I want to use PhysX like in this video:v=yZWri2DsIjI
But I have no clue how to make that in UE4, so can anybody explain it to me or link me to a tutorial on how to do that?

Here is another example:

Can somebody please help me with this?

May sound redundant. What kinda graphics card you have?

I think you will have to integrate nvidia gameworks first: https://forums.unrealengine/showthread.php?53735-NVIDIA-GameWorks-Integration :slight_smile:

Why do you want to know that?

Probably because FLEX is quite demanding and requires at minimum a Cuda 3.0 enabled card (So a GTX 650 or greater) and only works on NVIDIA GPUs at this time.
